First things first, but not necessarily in that order! — words of wisdom from Doctor Who The tweet below got me thinking about the importance of privacy. Data mining demands sound privacy policies in age of ‘big data’ http://t.co/1N0gZhz #datamining #BI #bigdata After all, in this day of age, with access to all sorts of disparate information, it becomes easier and easier to uniquely identify a person by their behaviors and external patterns. In Dr. Latanya Sweeney’s ground breaking paper k-Anonymity: a model for protecting privacy, she had noted the following startling observations: Based…

These are the slides on differential privacy case studies I had presented at the MindSwap on Privacy Technology, October 19–20, 2007. Center for Computational Thinking, Carnegie Mellon, Pittsburgh, PA.
Analyzing Data while Protecting Privacy – A Differential Privacy Case Study
Abstract Analysis and sharing of aggregate data (e.g., number of users whose favorite color is blue) is crucial to understanding patterns of the population being studied. The problem is that even summary data can expose the individuals who make up this information. Therefore, we are studying the use of privacy preserving data analysis techniques that will protect the individual and allow analysts to understand general trends. We believe that while there are unique perturbations of the data with these techniques, analysts will be able to use the data and protect the users at the same time. The case study involves…
